 ## Witness is a pluggable framework for supply chain security
 
- - It creates an evidence trail of the entire software development life cycle (SDLC) that can be used to evaluate policy compliance and detect any potential tampering or malicious activity.
- - It is designed to run in both containerized and non-containerized environments and does not require elevated privileges.
- - It supports most major CI and infrastructure providers, making it a versatile and flexible solution for securing software supply chains.
- - It uses a secure PKI distribution system and allows for verification of Witness metadata to further enhance security and mitigate against software supply chain attack vectors.

 ## Key Features
- - Implementation of the in-toto specification including ITE-5, ITE-6, and ITE-7, and an embedded rego policy engine for build policy enforcement.
- - Support for keyless signing with Sigstore and SPIFFE/SPIRE, and uploading attestation evidence to the Archivista server.
- - Support for RFC3161 compatible timestamp authorities
- - Experimental support for process tracing and process tampering prevention.
- - Verifies file integrity between CI steps and across air gap.
- - Support for Darwin, Windows, and ARM architectures.
- - Can use Archivista as an attestation store.
- - Integrations with GitLab, GitHub, AWS, and GCP.

 ## How it works
+
 - Witness wraps commands executed during a continuous integration process to create an evidence trail of the entire software development life cycle (SDLC)
 - It records secure hashes of materials, artifacts, and events that occur during the CI process
 - This evidence can be used to evaluate policy compliance, detect tampering or malicious activity, and ensure only authorized users or machines complete a step of the process

 Witness attestors are pieces of code that assert facts about a system and store those facts in a versioned schema. Each attestor has a `Name`, `Type`, and `RunType`. The `Type` is a versioned string corresponding to the JSON schema of the attestation. For example, the AWS attestor is defined as follows:
 
-```
+```go
   Name    = "aws"
   Type    = "https://witness.dev/attestations/aws/v0.1"
